N-Sea Group has entered into a long-term charter agreement with Rederij Groen for the newbuild offshore support vessel Dominus. The vessel is being constructed by Passer at Shipyard De Hoop in Tolkamer, the Netherlands.
N-Sea Group is a privately owned company headquartered in the Netherlands, with more than 500 people working offshore and onshore, on board vessels and in facilities across Europe and the Middle East.
During the last week of February, the keel laying ceremony of the new vessel took place. Delivery of the Dominus is scheduled for April 2027. N-Sea will operate the Dominus under full management and control.

Geophysical and subsea activities
With a length of 69.85 metres, a beam of 15.77 metres and a draught of 4.50 metres, the Dominus is engineered to support safe and efficient operations in the demanding North Sea environment. The vessel will be equipped to perform a wide range of advanced geophysical and subsea activities, including 2D/3D seismic and wide swath UXO surveys.
The 2031-GT vessel’s spacious deck layout (555 m2 clear deck space), lifting capacity (a Lagendijk LKC 800-500 with a capacity of 20 tonnes and an auxiliary Lagendijk crane, type Lagendijk LTC 25-1,5 (1.0)/8.8 (13,5)) and midship moonpool provide a platform for a significant expansion of N-Sea’s geotechnical capabilities, further enhancing the company’s integrated site investigation offering. The vessel can be operated by seven crew and accommodate 46 project staff.
Fleet expansion
The addition of the Dominus represents an important step in N-Sea’s long-term fleet strategy and demonstrates the company’s continued commitment to expanding and modernising its dedicated tonnage.
This investment follows the upcoming delivery of the survey vessel Geo Master in April 2026 and the newbuild cable installation and repair vessel Altera in June 2026. Together, these vessels are to strengthen N-Sea’s position as a provider of integrated subsea, survey and cable repair solutions across the offshore energy sector.

Careful consideration has also been given to further improving the safety and well-being of the crew.’
‘At Shipyard De Hoop, we believe strong partnerships are the foundation of successful projects. Working with Passer allows us to combine innovation, experience, and precision engineering,’ says Patrick Janssens, owner of Shipyard De Hoop.
